Research at Lawrence Berkeley National Laboratory's Advanced Light Source promises four-bit magnetic cells instead of the two-bit magnetic domains of standard magnetic memories. Magnetic vortices are whirlpools of magnetic field, in which electron spins point either clockwise or counterclockwise. In the crowded center of the whirlpool the spins point either down or up. These four orientations could represent separate bits of information in a new kind of memory, if controlled independently and simultaneously.

Berkeley Lab researchers have created the first fully integrated artificial photosynthesis nanosystem. While "artificial leaf" is the popular term for such a system, the key to this success was an "artificial forest."

Positioning itself to provide the most current technology and expertise to their users in order to address pressing energy and environmental scientific challenges, the DOE Joint Genome Institute announces six projects with which to launch the Emerging Technologies Opportunity Program. These new partnerships span the development of new scalable DNA synthesis technologies to the latest approaches to high throughput sequencing and characterization of single microbial cells from complex environmental samples.

Joint BioEnergy Institute researchers have developed an enzyme-free ionic liquid pretreatment of cellulosic biomass that makes it easier to recover fermentable sugars for biofuels and to recycle the ionic liquid.

By extending the coherence time of electron states to over half a second, a team of scientists from Lawrence Berkeley National Laboratory, the University of California at Berkeley, and Harvard University has improved the performance of one of the most potent sensors of magnetic fields on the nanoscale -- a diamond defect no bigger than a pair of atoms called a nitrogen vacancy center. The achievement is important news for nanoscale sensors and quantum computing.

Genome assembly, the molecular equivalent of trying to put together a multi-million piece jigsaw puzzle without knowing what the picture on the cover of the box is, remains challenging due to the very large number of very small pieces, which must be assembled using current approaches. As reported May 5 online in the journal Nature Methods, a collaboration involving DOE JGI researchers has resulted in an improved and fully automated workflow for genome assembly.
